Subject: collect! and Enumerable

Hi

I just noticed that Enumerable does not support collect! although
it does support collect. Was this changed from earlier versions?
If so, why?

irb(main):001:0> class M
irb(main):002:1> def each
irb(main):003:2> yield 1
irb(main):004:2> yield 2
irb(main):005:2> end
irb(main):006:1> end
=> nil
irb(main):007:0> class M
irb(main):008:1> include Enumerable
irb(main):009:1> end
=> M
irb(main):010:0> m=M.new
=> #<M:0x1892d0>
irb(main):011:0> m.collect { |i| i*2 }
=> [2, 4]
irb(main):012:0> m.collect! { |i| i*2 }
NoMethodError: undefined method `collect!' for #<M:0x1892d0>
        from (irb):12

Thanks
